Description

Technical Field

[0001] This utility model relates to the field of anti-over-clamping positioning technology, specifically an anti-over-clamping positioning device. Background Technology

[0002] An anti-overclamping positioning device is a device used to ensure that a workpiece maintains the correct position during processing. It fixes the workpiece in a predetermined position by clamping force to prevent it from moving or vibrating during processing. Clamping positioning devices play a vital role in fields such as machinery manufacturing and automated production.

[0003] Traditional positioning devices still have certain shortcomings in use: 1. Traditional positioning devices often have difficulty in accurately controlling the clamping force. Clamping too tightly may damage the workpiece, while clamping too loosely may not guarantee the stability of the workpiece position. Traditional positioning devices usually lack flexible adjustment functions and are difficult to deal with workpieces of different sizes or shapes, which limits their application range.

[0004] 2. At the same time, traditional positioning devices are not convenient for multi-faceted fixation, which means that in practical applications, operators often need to use other tools or devices to complete the auxiliary fixation of the workpiece. This not only increases the complexity of operation, but also reduces the stability of the work. Utility Model Content

Traditional positioning devices usually lack flexible adjustment functions and are difficult to deal with workpieces of different sizes or shapes, which limits their application range. At the same time, traditional positioning devices are not convenient for multi-faceted fixation, which means that in practical applications, operators often need to use other tools or devices to complete the auxiliary fixation of the workpiece. This not only increases the complexity of operation, but also reduces the stability of the work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An anti-pinch positioning device includes a mounting plate. A positioning component is provided on the top of the mounting plate, and an auxiliary component is provided on the bottom of the mounting plate.
